ESG Family Signal Generators Using Functions

Option 200 3GPP W-CDMA Base Station Performance Testing

Example Test Procedure

Follow this example procedure to perform a 3GPP W-CDMA dynamic range test on your

BS. Perform the procedures in the subsections sequentially, in the order in which they

appear in this document.

Subsection 1. Equipment Setup and Preliminary BER Verification

Complete the following steps to connect the equipment and perform a BER verification test

on your BS.

Figure 2-17 Dynamic Range Equipment Setup

1. Connect the BS to the test system as shown in Figure 2-17.

a. Using the appropriate cables, adapters, and antennae, connect the combined outputs

of the ESG system and AWGN signal generator to the RF input of the BS.

b. If the BS has multiple input ports, unused ports need to be terminated.

c. Connect the system controller and the BER test platform to the BS.

2. Measure the Bit Error Ratio (BER) of the BS.

The controller or BER test platform measures the bit error ratio of the BS exposed to

the RF output power at a typical amplitude. This process verifies that the BER of the

BS is within specification before introducing the AWGN interferer.

3. Record the first BER measurement result in the column titled, “Verification BER Value”

in Table 2-47.
